Has anyone had problems with Merc 7.4MPI Surging while underway? Noticed it yesterday for the first time. Has never happened before through the 1200 hours on the engines. Not terrible, but my starboard engine seemed to fluctuate about 2-400 rpm while cruising on calm water. It seemed to be more of a 'high' surge then any sort of bog (sync would stay even more often than starboard biased).
Fuel pump or filter issue? Fuel Issue? I still have my pre-winterization fuel in it but did stabilize it.
